The moon's Hayn Crater, located just northeast of Mare Humboldtianum, is an exquisite example of a complex crater. The central peak complex in the image above is dramatically illuminated by the low Sun casting long shadows across the crater floor. The floor of Hayn crater contains spectacular remnants of the impact event: impact melt, slump blocks, and complex debris. In some areas, rocks on the floor have cracked and eroded into fields of boulders.
